NUT-LOCK.

To -all whom it may-concern:

-Be' itflmown that I, VVEnsmR M Finn; minus, a citizen of the United States, residiingat \Vinston Salem, in. the county of For- .syth andfSt-ate oi -North Carolina, have invented a new and useful Nut-Lock of which: the-following is aspecification. v

'I his' invent-iq 1* has reference to improve ments in nut 1h s, and its object is t'o provide a simple "cheap and readily a plied. lookingdevice for nuts requiring no-c ange in the nut and but a slight modification of the bolt, while-the device isreadily detached when it is desired: to purposely remove the nut. v

In accordance with the present invention there is provided a plate of tough material, such as steel, having one edge bent to form' a nut engaging flange and the oppositeedge bent. sothat it may lie-readily forced into an easily constructed notch in the bolt after the nut has been appliedg-whiie the plate-is pm videdy' with a passage'for thethreaded shank oi the bolt and is shapedat the passagewith. a: thread engagving portion preventing any.

. movement of the nut lock lengthnvise (if the bolt shank.

While for conwenienoe of description the nut lock will be considered as appliedto a. nut in turn applied to-the threaded-portion of a: bolt, it will be: understood that the device is .equwllyjapplgioable toany nut-likestruoture applied. to,a:ny threaded member whenit is desinazble thatfthenun be held against aiocidenflal turning even under the most" severe shocks and? jars towhich it may be subjected. use,. and. the terms nut and bolt'are tdbe understood as applicable not only to structures specifically descnibed' by 40 the terms-,- but to any lilie strue hures where the invention is'ap'plicable.

The invention will be best understood from a oonsidesatien of the 'fiollowing detailed description, taken in connectionwith the accompanying drawings forming part of this. specification, with the further understanding that while the drawings show' a practical form ofthe invention, the latter is .not confined to any strict conformity with the showing of the drawings, but may be changed and modified so long as such changes and modifications fall within the scope of the appended claims.v p

there is appliedi anut: 2 which may be a lm'i taken as indicative of any member ofwlilie character. i v y {J The nut lock designed to hold the nutzlioit 55 the threaded portion oi tli bolt 1 against;- turning, is formed of a plabe 3 whiclrnia F "idedt at an intenniediaee lpoint a a sage 4 01 a. diameter. to permifisfl ef 3 80 to slip over the threaded pohtiontg 'r gig. l iollzg 1.

The extensioninr lip may he nanrowedmt I asshowntin Figs. land 5; v i k The Wald of the passage on opening: 41110- Ward; the lip- 5 isbeveledilto iorml. mzcurved tooth 8- shaped: to enter between-two adju cent tunes oflihethr p but the free opening of. -he'passeg'4. i sufli cient to permit the placing. oi thelate 3 on to the nut with the threaded end of the ioo . bolt protruding.

When the nut2 has been screwed onto the bolt-to the desired extent, oneside ofthe threaded portion ,ofthebolt is' acted upon by a file or gold chiselto form a notch 9 into which the return-end of the lip 6 is forced by folding the lip6 ,down upon the body portion of the plate in a .direotiontoward the opening i or shank of th abolt. This causes two adjacent turns of the thread of the bolt and the lip 5 is'so locatedwith-reference to enal ze "11 t ey ,1

the tooth 8 that under these circumstances it is brou ht into contact or into operative relation with the adjacent side of the nut.

The position of the parts after the nut lock has been placed upon the shank of the bolt amtil-it rests upon the outer face of the nutwith the tooth 8 lodged between two adjacent turns of'the threadand before the nut lock is' finally secured to the bolt, is shown in Fig. 3, while the ,final position of the parts is illustratedh Figs. 1 and 2. The lip 6 is readily forced down upon the plate -3 and into the notch 9 by any suitable tool such as a unch, and when once in such position no orce less than one destructive to the parts .18 sufiicient to turn the nut on the bolt, wherefore thenut is securely locked ,in place and cannob accidentally loosen.

Suppose, however, that it is desired to remove the nut, then a chisel or other tool forced between thelip 6 and theshank of the bolt readily bends the lip 6 away from the bolt sufficiently to permit the removal of the plate 3 from the nut, whereupon the latter may be removed at will.

When the lip 6 is forced into its seat in the notch 9-any. means, such as a clamp or a wrench, is applied to the nut 2 so as to "hold the lip 5 tight against the corresponding side of the nut, thus permitting the bending of the lip 6 into position without at the "same time dislodging the tooth 8 from its seat between two ad acent turns of the threaded portion of the bolt.

The structure shown in F igs. 1 to 5 isthat adapted to square nuts, while the nut shown in Fig. 6 is one adapted tofhexagonal nuts, in which case there is a plate 3 of generally hexagonal form having 'lips 5 and (5, the latter being rovided with a terminal por tion 7 like t at of the other form and the plate 3 having an opening 4'with a marginal tooth 8 on one side as in the other form. 'The operation of the structure shown in Fig. 6 is the same as that shown in the other figures.

What is claimed is 1. A nut lockcomprising a plate having lipsatopposite ends pro ecting from respectively opposite faces of the plate. each at an angle thereto, and said plate having a passage intermediate of the lips and-of a size to permit the plate to he slipped over the threaded shank of'a bolt and to then be moved laterally with respect to the longitudinal axis of the bolt, said passage being formed on the side toward one of the lips with a tooth adapted to lodge between adjacent turns of the threaded end of the bolt.

2. A nut lock comprising a plate adapted to one face of a nut, said plate having one end bent at an angle to engage the corresponding side of an applied nut and the other end also bent at an angle from the face of the plate remote from that with respect to which the first-named end is bent and the second-named end having a reversely bent continuation, and said plate being provided with an intermediate passage for the threaded end of a bolt with a tooth at the margins of the passage directed toward the center thereof and shaped to enter between adjacent turns of the threaded end of the bolt to which the nut lock is applied.

3. The combination with abolt and nut threaded thereon, of a nut lock comprising a plate having a passage therethrough and adapted to be passed on to the threaded end of the bolt into engagement with the nut. one end of the plate being turned to form an angle lip adapted to engage the corresponding side of the nut, and the passage having an inwardly directed tooth shaped to enter between adjacent threads of the threaded end of the bolt, the other end of the plate being bent into a lip project-ing in a direction opposite to the first-named lip and terin a return portion, and the minating threaded end of the bolt being formed with a notch or seat adapted to receive the return portion of the last-named lip when the latter is folded down upon the plate.

In testimony, that I claim the foregoing as my own, I have hereto aflixed n1 signature in the presence of two witnesses.
